Taking Photographs-Focus Focus To select the AF-area mode, set the function dial to [+] and rotate the main command dial. The current AF-area mode is indicated by the focus-area display in the control panel: Single-area AF Dynamic-area AF Predictive Focus Tracking If the camera autofocus system detects that the subject is moving when the shutterrelease button is pressed halfway, it will automatically initiate predictive focus tracking. If the subject is moving toward or away from the camera, the camera will track focus while attempting to predict where the subject will be when the shutter is released. In single-servo autofocus, the camera will initiate predictive focus tracking if the subject was moving when the shutter-release button was pressed halfway. Focus will lock when the subject stops moving. In continuous-servo AF, the camera will also initiate predictive focus tracking if the subject starts moving after the shutter-release button is pressed halfway. Focus will not lock when the subject stops moving. If AF-ON is selected for Custom Setting 14 (AE-L/AF-L), predictive focus tracking will also take effect when the AE-L/AF-L button is pressed. Predictive focus tracking is not available in manual focus mode. 66
